Question

Is this possible?

I have a function which accepts a user string and then splits into an array of words. I’m going to sort the array and de-duplicate it.

However, it will be used in a function which is called in an iterative step. It actually iterates over a database and checks for each word in the user defines string in each field.

I would like to only sort and de-dup the array once but call the function many for that particular instance of the class. Should I just store the sorted array in a static instance variable?

Thanks for your time

My code is something like this (pseudo-code):

  public class searchAssistant{
        private float mScores[][];
        private Cursor mCursor; 

        public searchAssistant(Cursor c){
            mCursor = c; 
        }

        private float scoreType1(String typeFromCursor, String typeFromUser){
             if (typeFromCursor == typeFromUser) {return 1}
             else {return 0}

        }

       //similar method for type scoreType2 but sorting an array



       private int[] scoreAll(){
          int 1 = 0; 

         do {
             mScores = ScoreType1(mCursor.getString(), smomeString) + scoreType2(...);
              itr++;
            } while(cursor.moveToNext)
            return mScores;
       }

 }

is this the wrong way to be doing things?

Answer 1

No. Change the signature of the method called multiple times to make it accept the array, and compute the array before calling the method:

Instead of

String s = "...";
while (someCondition) {
    someMethodCalledMultipleTimes(s);
}

Use something like this:

String s = "...";
String[] array = computeTheArrayFormTheString(s);
while (someCondition) {
    someMethodCalledMultipleTimes(array);
}
